General Description
The G5657 is a monolithic step-down switch mode regulator with a built in internal power MOSFET. It achieves 3A continuous output current over a wide input supply range with excellent load and line regulation.
Current mode operation provides fast transient response ans eases loop stabilization.
Fault condition protection includes cycle-by-cycle current limiting, output short circuit protection and thermal shutdown. In shutdown mode the regulator draws 25µA of supply current. Programmable soft-start overwrites...
